Application filed November 1, 1905. Serial No. 285,498.

To all whom it may concern:

-Be it known that I, AUGUsT LEYERLE, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Air-iioistening Devices, of which the following is a specification.

This invention relates to devices for adding to the humidity and supply of fresh air in a room or dwelling; and the general object of the invention is to provide a device which is regulable to vary the condition of air-moisture from nil to overabundance; and it 0011-,

sists in the novel apparatus and its combination of parts hereinafter described in detail, illustrated in the drawings, and incorporated in the claims. 1

In the accompanying drawings, forming a part of this specification, F igure 1 is a front view of a device embodying my invention. Fig. 2 is an end view thereof. Fig. 3 is a top plan view. Fig. 4 is a transverse section in elevation taken on line X X of Fig. Fig. 5 is a perspective view of the parts shown in Fig. 1. Fig. 6 is an enlarged fragmentary "view showing one end and journal of the hol- ,low roller for the wick and moistener.

Referring in detail to the several views in the drawings, 2 represents a tank or receptacle adapted to contain a liquid 3, which ordinarily would be pure water." This tank Or receptacle is shown with a high back 4, to which is fastened a spring-catch 5, adapted to hold the roller- 6 in an elevated position. The roller 6 is journaled in the free ends of a pair of arms 7 and 8, pivoted at 9 and 10 to tte ends of the tank 2. The pivot 10 is in t e form of a bolt, having a thumb or butter fly nut 11, by means of which the arm 8 may be clamped against the end of the tank when t is ivots 9 and 10. On the squared end 12 o t e rollen-shaft 13 or axis of roller 6 is mounted a crank 14, by means of which the roller 6 may be rotated. The roller 6 carries a cloth, tl ie wick end 15 of which normally dips into the liquid 3, while the moistener or evaporating portion hangs over the roller on the outside of the tank 2. The evaporator or moistener 16 is preferably provided with a rod or Weight 17 in its lower edge or hem. The cloth comprising the moistener and wick to produce the best results must be constructed in a special manner or consist of a weft. wherein the threads run chiefly at right angles to the long axis of the roller 6.

sid arms 7 and 8 are rotatably adjusted on However, this feature forms no part of the present invention and need not, therefore, be described in detail. The roller 6 is preferably a hollow brass cylinder closed at its end to exclude moisture from its interior, and the moistener and wick is fastened, so that it will not slide over the roller. I have shown a pair of hooks or points 18, which project from the roller 6 and penetrate the cloth. These hooks will permit the relative adjustment of wick and moistener to a limited extent and serve to illustrate the idea-of adjustment, to be referred to more fully hereinafter. Screw-holes 19 19 in the back 4 provide means for suspending the device upon the wall of a room.

The operation of my invention is as fol.- lows: Water is taken up from the tank 2 through the wick portion 15 by capillary attraction. As the distance through which liquid can be raised in this manner is limited and it is desirable that the evaporating area.

should be more or less extensive, I provide the overhanging portion 16, which I term the moistener. The exposures of the moistenor and wick are relatively variable by rotation of the crank 14, and the sa uration of the wick alone is variable by raising or lowering the roller 6 about the axes 9 and 10. If

the wick saturates the moistener too rapidly, the set-screw or thumb-nut 11 is loosened, the arms 7 and 8 rotated upwardly to the desired extent, and the nut again tightened. The normal length of the wick is preferably made so that its lower edge will be raised entirely out of the liquid when the roller is in its highest position, held by catch 5, as indicated by dotted lines in Fig. '2. From the latter point the depth of the dip of the wick can be varied to a nicety and according to the requirements of a room, as may be indicated by an instrument for recording the percentage of moisture in the air, &c., or according to th appearance of the moistener and the degre of moisture thereon. As the evaporation o the liquid into the air of a room depends as to its rapidit upon the existing temperaturev an pressure, no fixed arrangement or invariable exposure of moistener and wick will answer the purpose undcr all circumstances. The adjustments whereby the wick may be shortened entirely v or lengthened and a corresponding inverse variation made in the length of the moistener,

as well as the variability of the dip of the wick, adapts the device for rooms of different sizes and obviates the necessity of providing difi'erent sizes of evaporators for different rooms,which different sizes are not, as stated, to serve acceptably under varyin conditions of temperature and pressure un ess the ab sorbent and evaporator are adjustable to vary exposures and depths of dip into the liquid. In practice the Water in tank 2 is often treated to increase its volatility as, for instance, with turpentine'or charged with a germacide or disinfectant, such as formaldehyde or the like.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, With a vessel for liquid, of a roller, a cloth suspended upon said roller so that one end thereof normally di s into said vessel and the liquid therein and the other end is exposed to the atmosphere, means for rotating said roller to vary the length of cloth on each side thereof, and means for swinging said roller in an arc 'to either lift the immersed end of said cloth out of the liquid or to vary the depth of its dip thereinto 2. The combination with the vessel 2 open at its top, with means for suspending said vessel upon the Wall of a room, a pair ofrotatable arms pivoted to move over the opening into said vessel, a roller 'ournaled in said arms, a crank, or the like ior rotating said roller, a cloth, or the like, hung over said roller so that one end normally dips into said vessel and the opposite end hangs outside of said vessel, and means for lockingsaid arms in different radial positions relative to their axisor axes of rotation.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
